Abstract

Abstract

Objective To analyze the changes in birth weight of neonates before and after the coronavirus disease 2019 (COVID-19) epidemic and its influencing factors. Methods Birth surveillance data from 2017 to 2023 in Hebei Province were collected, and the study subjects were divided into three groups: the pre-COVID-19 group (2017-2019), the during-COVID-19 group (2020-2022) and the post-COVID-19 group (2023). Results The average birth weight of newborns in Hebei Province was (3 287.06±504.97) g, which was lower than that before the COVID-19 epidemic (3 351.86±493.70) g. The prevalence of low birth weight also increased from 3.77% (5 279/140 147) to 4.99% (1 135/22 755), and the prevalence of macrosomia decreased from 9.00% (12 618/140 147) before the COVID-19 epidemic to 6.84% (1 556/22 755) after the epidemic. The multivariate logistic regression analysis model after adjusting for other risk factors showed that the incidence of low birth weight after the COVID-19 epidemic was 1.163 times higher than that before the COVID-19 epidemic (OR=1.163, 95% CI: 1.061-1.275), of which the incidence of mature low-birth weight was 1.248 times that before the COVID-19 epidemic (OR=1.248, 95% CI: 1.104-1.412), and the incidence of preterm low-birth weight was 1.246 times that before the COVID-19 epidemic (OR=1.246, 95% CI: 1.150-1.350), there was no significant effect on preterm low birth weight during the COVID-19 epidemic (P>0.05). The COVID-19 epidemic, advanced maternal age, low level of education, inadequate number of prenatal check-ups, female infants, high level of delivery hospitals, and pregnancy complications are risk factors for low birth weight, The rate of preterm low-birth weight in tertiary hospitals is higher than that in primary and secondary hospitals. Conclusions After the COVID-19 epidemic, the birth weight of newborns in Hebei Province has decreased compared with that before the COVID-19 epidemic, and the incidence of low birth weight infants has increased. High risk populations should be identified, prenatal check ups and prenatal care should be strengthened, and the occurrence of low weight should be reduced.
